WALTER MARTIN IWIUSGRAVE, OF BOLTON, ENGLAND.

DEVICE FOR LUBRIOATING ENGINES.

SPECIFICATION forming part of Letters Patent No. 628,279, dated July 4, 1899;

Application tiled January 16, 1899. Serial No. 702,337. (No model.)

To a/ZZ whom, it Wtwy concern:

Be it known that I, WALTER MARTIN MUS- GRAvE, a subject of the Queen of England, residing at Bolton, in the county of Lancaster, England, have invented certain new and useful Improvements in Devices for Lubricating Engines, of which the following is a specification.

This invention relates to improvementsin the construction of vertical compound steamengines and in apparatus for automatically lubricating the same and is designed and arranged in a compact and self-contained manner. 4 e

On a framework of box form is mountedran inclosed stand'or frame provided With a door or cover secured in any convenient manner. On the upper end of the said stand or frame are mounted the high pressure and lowpressure cylinders, provided with pistonvalves and valve-boxes,by which thecylinders are brought into close proximity with each other. Inside the stand or frame are disposed slide-bars, on which are mounted slide-blocks connected with the head of each( piston-rod.

The piston-rods are coupled to balanced sweep-` cranks by connecting-rods. The crank-'shaft is mounted in side and middle bearings and is provided at one end with whatis well known as a crank-shaft governor77 for regulating the speed of theengine. If desired, any other suitable governor may be employed for operating a throttle-valve. The valve-spindles and piston-valves are operated by eccentrics and rods from the crank-shaft. The latter is provided with a ily-wheel or a strap or rope pulley for transmitting power by belt or ropes, or the crank-shaft may be coupled direct to any machine. The crank-shaft governor and the eccentrics for operating the valves are inclosed in stationary boxes or covers containing oilor lubricant. l 4

My improved apparatus for automatically lubricating the movable parts, wearing-surfaces, and the like of vertical engines consists in providing the base or foundation plate' with an oil well or reservoir in. which is located a pump, the ram 'of which is actuated by an eccentric and rod or other mechanical means from the crank-shaft. The pump is fitted with 'valve-boxes and valves onthe ball or other principle. The oil orlubricant is raised from the Well or reservoir and forced through pipes to a box or chamber, which is providedon each side with a parallel motion consisting of pipes and couplings to compensate for the vertical movements of the cross-head,to which the same is attached. The oil or lubricant is forced into'the cross-head pin on one side to lubricate, from whence it is forced bythe pump out on the other side and down pipes connecting the same with the crank-pin. In lieu of the before-mentioned parallel'motion I insert in each slide-bar a pipe-coupling by means of a passage with the surface of the slide-bars, and by the movements of the slideblock of the cross-head the surplus oil or lubricant is admitted through an opening to the center pin of the cross-head, attaching the connecting-rod thereto, from whence the oil or lubricant tlows down a pipe to the crankpin.` To the main pipe leading from the oilpump are coupled other pipes, from which oil or lubricant ilows to the .crank-shaft bearings, the surplus flowing back to the oil well or reservoir to be used over again. For the purpose of lubricating the eccentric for pump and other parts suitable drip7 pipes and taps may be employed. The eccentric may be lubricated by oil or lubricant which flows tact with suitable openingsand a plate secured to the eccentric-ring. The pipes are tted with union joints and couplings where necessary for the purpose of fixing or removing the same when desired or necessary. The crank-shaft and other parts are provided, where necessary, withdripping-points to prevent oil or lubricant being drawn or forced outside the framing, thus insuring outside cleanliness. i

In all the figures the same letters are employed to indicate corresponding parts.

C is the high-pressure cylinder; D, lowpressure cylinder 5 E, high-pressure-cylinder piston-rod; G, low-pressure-cylinder pistonrod; H, connecting-rods; I, balanced sweepcranks; J, crank-pins; K, crank-shaft; L, crank-shaft pedestals; l\I,tiy-wheel; N, eccentrics; O, eccentric-rods; P, valve-spindles; Q, valve-boxes, and R foundation or framework of box form.

On the foundation orframeworkRismounted the inclosed stand or frame S, provided with the door or cover T, secured in any convenient manner. On the upper end of the stand or frame S are mounted the high-pressure cylinder C and t-he low-pressure cylinder D, provided with the valve-boxes Q, the latter being tted with the piston-valves U. The valve-boxes Q are disposed on the outside, by which the steam-cylinders C and D are brought into close proximity with each other. Inside the stand or frame S are disposed the slide-bars V, on which are mounted the slide-blocks lV, connected to or formed with the heads X of the piston-rods E and G. The piston-rods E and G are coupled to the balanced sweep-cranks l and crank-pins J by the connecting-rods H. The crank-shaft K is mounted in the side or middle bearings or pedestals L, being held therein by the caps Y, secured by bolts. The valvespindles P and piston-valves U are operated by the eccentrics N and eccentric-rods O from the crank-shaft K. The latter is fitted with the ily-wheel M, which may be substituted by a strap or rope pulley for transmitting power by belts or ropes, or the crank-shaft K may be coupled direct to any machine by means of the shaft a and coupling b bolted to the boss or center c of the fly-wheel M, as shown in Figs. l, 3, and -l in the annexed drawings. The eccentrics N for operating the pistonvalves U are inclosed in the stationary boxes or covers d, secured by bolts or their equivalents to the sides of the stand or frame S and the foundation or framework R.

My improved apparatus for automatically lubricating the movable part-s, wearing-surfaces, and the like of vertical engines consists in providing1 the foundation or framework R with the oil well or reservoir f, in which is located the pump 71., the ram j of the same being actuated by the eccentric l and rod m from the crank-shaft K. The pump 7L is iitted with the valve-box n, provided internally with valves 011 the ball or other principle. The oil or lubricant is drawn from the oil well or reservoir f through the suctionpipe p into the valve-box n by the outward stroke of the ramj and forced from the same by the downward stroke, which forces the oil or lubricant up the pipe o' and through the valve into the pipes r, connected with the caps or covers Y of the crank-shaft pedestals L. The pipes u are provided with the couplings fc, secured to the underside of the slidebars V and in line with the passage w, leadin g to the slide-blocks lV on the slide-bars V, and as the slide-blocks XV slide or move up and down the oil orlubricantis forced through the hole or passage a2 into the cross-head pin b2 to lubricate the center b2, from whence the oil or lubricant is forced by the action of the ramj` of the pump out through and down the pipes z, connecting the same with the crankpins J. By this arrangement the surplus oil or lubricant flows back to the oil well or reservoir f to be used over again, the operation being continuously repeated as long as the engine is in motion. The crank-shaft K is provided with the dripping-points s, turned or formed thereon to prevent oil or lubricant being drawn or forced outside the framing of the engine.

The arrangement of my improved apparatus for lubricating the aforesaid movable parts by means of a parallel motion, as shown in Figs. 4 and 5, consists in providing the foundation or framework R with the oil well or reservoir f, in which is located the pump h, the ramj ot' the same being actuated by the eccentric Z and rod m from the crank-shaft K. The pump 7L is fitted with the valve-boxes n, provided internally with valves on the ball or other principle. The oil or lubricant is drawn from the oil well or reservoir f through the suction-pipe p into the valve-box n bythe outward stroke of the raln j and forced from the same by the downward stroke of the ram, which action forces the oil or lubricant up the pipe r and through the T o" into the pipes o, leading to the caps or covers Y of the crankshat't pedestals L. The pipes 1J are provided with the coupling x, secured to the box or chamber m2, which is provided on each side with a parallel motion, consisting of the pipes h2 and couplings i2, to compensate for the vertical movements of the cross-head X of the piston-rods E and G. The oil or lubricant is forced by the action of the pump h through the pipes h2 and couplings t2 into the crosshead pins b2 on one side to lubricate the same and from whence it is forced out on the other side by the action of the pump h and down the pipes z, leading to the crank-pins. The oil or lubricant also passes up the pipe s2 and through the aperture t3, from whence the slides V are lubricated. The surplus oil or lubricant, which iiows back to the oil well or reservoir f, is used over and over again as long as the engine is in motion. For lubricating the eccentrics N each end of the pipe c is provided with the pipe o4.

The pipes for conveying oil or lubricant are fitted with union joints and couplings where necessary for the purpose of fixing or removing the same when desired or necessary.

If desired, the engine may be provided with what is known as a crank-shaft governor IOO IIO

IZO

\ ZA', (shown in Figi of the drawings,) or any other suitable' governor may be employed for operating a throttle-valve. In case an ordinary ball or other governor is employed for controlling the speed of the engine it maybe iiXed in any desired position and driven by bands or ropes from the grooves a6 on the end of the crank-shaft K.

Having now particularly described and ascertained the nature of my said invention and Vin what manner the same is to be performed,

' I declare that what I claim is- 1. The combination with the framework having oil-reservoir, of the crank-shaft, a

pump located in said reservoir, an eccentric on saidshaft connected with the pump, pipes leading from the pump to the parts to be lubricated,couplings on said pipes and branches leading therefrom to other parts to be lubricated the cross-head and Yslide-blocks having my hand in presence of two subscribing wit- HGSSGS.
